#     kbuild: allow to run dt_binding_check without kernel configuration
#     
#     The dt_binding_check target is located outside of the
#     'ifneq ($(dtstree),) ... endif' block.
#     
#     So, you can run 'make dt_binding_check' on any architecture.
#     This makes a perfect sense because the dt-schema is arch-agnostic.
#     
#     The only one problem I see is that scripts/dtc/dtc is not always built.
#     For example, ARCH=x86 defconfig does not define CONFIG_DTC. Kbuild
#     descends into scripts/dtc/ with doing nothing. Then, it fails to build
#     *.example.dt.yaml files.
#     
#     Let's build scripts/dtc/dtc forcibly when running dt_binding_check.
#     
#     The dt-schema does not depend on any CONFIG option either, so you
#     should be able to run dt_binding_check without the .config file.
#     
#     Going forward, you can directly run 'make dt_binding_check' in a
#     pristine source tree.
